nVidia GeForce & LCD display problem


I've recently installed Windows XP and RedHat 9.0 on a new computer with a nVidia GeForce 5200 card and a FPD1530 LCD monitor. The graphical installation didn't work, so I went through the text installation which worked fine. Now, when I try to boot to Linux, it initalizes but once the graphical interface is about to come up the monitor turns off as it were recieving no signal. Right now I'm only using the generic VESA driver which seems to be not working right. Is there something I can do to resolve this? If I need to download new drivers, how can I drop into a text line to be able to download the drivers?

First go to the Nvidia site and get download this driver to your /home/<username> directory. NB: It's not the latest from Nvidia, but too many people have had problems with that one and not this one. While you're at it, read the README - Text Version file, or download it also. You need to especially read (sec-02) INSTALLING THE NVIDIA DRIVER and (sec-03) EDITING YOUR XF86CONFIG FILE before you begin.

To "drop to a text line" you can do Ctrl + Alt + Backspace to get to a command line. The problem you're having may be the refresh rate for your monitor. If you can get to a command line and edit your /etc/X11/XF86Config-4 file, you should be able to boot to a GUI. I think that's the correct filename for RedHat, but I'm not sure. If that's not it, browse the LQ RedHat forum and you can find the name. Or, from cli (command line interface) you can type
$ locate XF86Config
or
$ locate XF86Config-4
and find the file.

Actually, in Slack you could just run
$ xf86config
and configure the file. Try that in RedHat.

What you need to set in that file are the horizontal and verticle refresh rates for your monitor. If you don't know them, maybe you could start with what my Philips LCD uses and go from there ->
Code:
# **********************************************************************
# Monitor section
# **********************************************************************

# Any number of monitor sections may be present

Section "Monitor"

    Identifier  "Philips LCD 150B4"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    HorizSync   31 - 60.0

#    HorizSync  30-64         # multisync
#    HorizSync  31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync  15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    VertRefresh 56-76

Sorry for so much stuff. I'm walking out the door and that's the quickest way to give you help I know.

Question blank screen

Your problem sounds just like a problem I had. Dr Orz helped me by telling me add a line to the X server. Here is what he said to do.

underneath where it says Driver "nvidia" in your XF86Config file, add the following line ::
Option "IgnoreDisplayDevices" "DFP, TV"

You can also do this through the GUI configurator using the add option button. In that case, do not use the quotes.
Also, I do not know if you should include the DFP, which I think stands for Digital Flat Panel, since you are using a LCD.
Good luck and let us know how things go.

Thank you two. I finally got it working. After switching to a CRT monitor, some download, using a Knoppix CD to move files, and finally playing with XF86Config, I got it working. Thanks!

Wait a minute there. Did you get your LCD monitor to work properly,
or did you give up and use a CRT? Are you now able to use your
LCD monitor in RedHat?

Talking This is the big problem I'm passing through

Red Hat could really think about this problem... I'm trying miserably to fix it.
